This we would have been under the 1976 act which, here, applies to
works not already in the public domain. So we would need to know if the original copyright was extended, under the rules of the 1909 act.
But the 1909 act says-
If no notice of copyright was affixed to a work and the work was "published" in a legal sense, the 1909 Act provided no copyright protection and the work became part of the
public domain.
So was there such a note affixed to all the copies?
If so, the copyright lasted to 1997 and so the 1976 act would apply. apropos, the 1985 copyright application above.
This would put the term of protection to 75 years after publication to 2017. or 50 years after Adams death which would be 2034.
If this is so then the photograph falls under the Sonny Bono act.
It all goes back to whether the prints and publications between 1942 and 1976 all had a copyright affixed to the work. Most particularly I am thinking the
U.S. Camera Annual 1943. Anybody have a copy?
